This adds a new setting `enableConsistentCompileAnalysis`,
which enables the new "Consistent" Analysis format,
which is faster and more repeatable than the status quo.
This is initialized to `true` by default.
It can be opted out either by the setting or using
`-Dsbt.analysis2024=false`.
When a macro was compiled against a new scala-library (say 2.13.15),
the runtime classpath of the Scala compiler should not contain an older
scala-library. Otherwise the macro can cause a NoSuchMethodException
during expansion.
This commit updates scala-library in the scalaInstance to the version
on the projects dependency classpath.
The `csrSameVersions` setting can be used to keep dependencies at the
same version.
By default it's used for Scala artifacts. They need to be kept at the
same version because the compiler / reflect are built with
cross-artifact inlining enabled.
`csrSameVersions := Seq(Set(scala-library, scala-reflect, scala-compiler, scalap))`
Users can make use of the new setting in the following way:
- `csrSameVersions += Set[InclExclRule]("com.corp" % "lib", "com.corp" % "lub")`
- `csrSameVersions += Set[InclExclRule]("com.corp" % "lib-family-*")`
When expanding a macro compiled against a new Scala library, the
runtime classpath of the compiler should not contain an older library.
Otherwise a NoSuchMethodException can occur.
A similar issue is present when running the Scala repl through sbt.
An input line compiled against a new library could fail to run if
the repl's runtime classpath is on an old version.
There are a couple of settings / configs that affect this, summary
below. The change in this PR seems to be the most narrow.
`scalaModuleInfo.value.overrideScalaVersion` in sbt
- affects how sbt to sets coursier's `forceScalaVersion` (see below)
- used by librarymanagement.ivy. If true, add a OverrideScalaMediator
See sbt/sbt#2634. Probably not relevant when using coursier.
`autoScalaLibrary` setting in sbt
- automatically add `scala-library` (or `scala3-library`) as a project
dependency
- also used for `forceScalaVersion` (see below)
`CoursierConfiguration.autoScalaLibrary`
- if `true` then Coursier `ResolutionParams.forceScalaVersion` is set
to to `true`
- initialized by sbt to
`autoScalaLibrary.value &&
!ScalaArtifacts.isScala3(sv) &&
!Classpaths.isScala213(sv) && // added in this commit
scalaModuleInfo.forall(_.overrideScalaVersion)`
coursier `ResolutionParams.forceScalaVersion`
- if true, `scala-library` / `scala-reflect` / `scala-compiler` /
`scalap` are forced to the scala version, not actually resolved
- for Scala 3, the `scala3-library` and `scala3-compiler` versions
are forced
